Fixes: https://github.com/spring-projects/spring-integration/issues/3366
When the same path is mapped for integration HTTP endpoint and MVC
method mapping, but different other mapping options (e.g. method)
and one of them fails to match, there is no way to try other
`RequestMapping` from the `DispatcherServlet` because
`RequestMappingHandlerMapping.handleNoMatch()` throws an exception
when no match instead of `null` according chain of responsibility logic
in the `DispatcherServlet`
* Rework `IntegrationRequestMappingHandlerMapping.handleNoMatch()` to catch
all the super exception and return `null` to the `DispatcherServlet` to let
it to try other `RequestMapping` from the configuration
* Change an order for `IntegrationRequestMappingHandlerMapping` to `-1`
to let it to be tried first before regular MVC `RequestMappingHandlerMapping`
* Add a test-case to ensure that mix-in Integration HTTP and MVC for the
same path works as expected without failing on first try
